Question

necesito la respuesta de esta ecuacion​

Answer 1

Respuesta:

$\frac{2x + 1}{x + 4} - 7 = \frac{6 - 2 {x}^{2} }{x + 4} \\ \frac{2x + 1 - 7(x + 4)}{x + 4} = \frac{6 - 2 {x}^{2} }{x + 4} \\ \frac{2x + 1 - 7x - 28}{x + 4} = \frac{6 - 2 {x}^{2} }{x + 4} \\ \frac{ - 5x - 27}{x + 4} = \frac{6 - 2 {x}^{2} }{x + 4} \\ - 5x - 27 = 6 - 2 {x}^{2} \\ 2 {x}^{2} - 5x - 27 - 6 = 0 \\ 2 {x}^{2} - 5x - 33 = 0$

${x}^{4} + 2 {x}^{3} - 7 {x}^{2} - 8x = - 12 \\ x( {x}^{3} + 2 {x}^{2} - 7x - 8) = - 12$
